Efficacy of Inhaled Cannabis on Painful Diabetic Neuropathy

Researchers at the University of California, San Diego performed a randomized, double-blinded, placebo controlled crossover study in 16 patients with painful diabetic peripheral neuropathy to assess the short-term efficacy and tolerability of inhaled cannabis. This trial of inhaled cannabis demonstrated a dose-dependent reduction in diabetic peripheral neuropathy pain in patients with treatment-refractory pain. This adds preliminary evidence to support further research on the efficacy of cannabinoids in neuropathic pain.
